We've encountered that problem numerous times.
Unscrew the yoke/head assembly from the bowl and reconnect it to the
bowl with a 2-3 foot length of hose and the appropriate fittings. Hold
yoke/head assembly over a 5 gal bucket that has been marked off in
gallon increments. (We use a janitor's style drum marked off in 5
gallon increments for showers). Activate the eyewash and record time it
takes to fill the bucket 1 gal and then do the math. You can also check
the dispersion at this time with a Haws or Guardian Plexiglas
gauge...just make sure you hold the yoke/head assembly level to the
plane of the floor.
